【摘要】 介绍了季铵型阳离子变性淀粉黏度及其热稳定特性,以及阳离子淀粉与原甘薯淀粉黏度的变化,确定了制备阳离子淀粉的最佳反应条件为:控制反应体系的pH值为11,反应时间为5h,醚化剂用量为淀粉投料量的25%,反应温度为50℃。更多还原

【Abstract】 The viscosity and thermal stability of quaternary cationic starch was introduced. And the variation in viscosity of cationic starch and original starch from sweet potato was investigated. It was indicated that the optimal conditions for cationic starch preparation were: pH 11, time 5 h, temperature 50℃ and 25% etherification agent (m/m) to whole addition amount of starch.更多还原
